Have you or someone you know been told by a doctor about a condition called ' Hydrocephalus ' and that a 'VP Shunt' should be placed as a treatment for it? It's normal to feel a little scared, nervous, and have a big question about what this is. So today, let's talk about what this VP Shunt is, what it does, and how it is placed, in a simple way that you can understand.
What conditions are treated with a VP shunt?
Simply put, a VP Shunt is used to treat a condition called Hydrocephalus . Now you may be wondering what that is.
There is a special fluid that surrounds our brain to protect it. We call this Cerebrospinal Fluid (CSF) . It is like the shock absorbers in a car. It protects the brain by preventing it from jolting and jolting. It also helps to carry the nutrients it needs and remove waste products from the brain.
But sometimes this CSF fluid can be produced in excess, or it can be reabsorbed by the body without being properly reabsorbed. Then this fluid accumulates inside the brain, causing a lot of pressure on the brain. That's what we call Hydrocephalus. This pressure can cause various symptoms .
| Common symptoms of hydrocephalus | |
|---|---|
| Headache | Vomiting and nausea |
| Constant fatigue | Confusion |
| Problems with walking and balance | Vision problems |
How does this VP Shunt actually work?
A VP shunt is a very thin plastic tube that is used to drain excess CSF fluid from the brain to another part of the body, usually the abdominal cavity (inside the belly). There, the fluid is absorbed by the body.
This tube system has a special valve (one-way valve). This allows the fluid to flow only in one direction, away from the brain. The doctor sets a specific pressure setting for this valve. When the CSF fluid in the brain increases and the pressure exceeds that set point, this valve opens and the extra fluid flows into the abdomen. When the pressure returns to normal, the valve closes. A very simple, but very important process.
Are there two types of shunts? (Fixed and Programmable)
Yes, there are mainly two types of these valves.
1. Fixed Valve Shunts: The pressure level of these types of valves is determined before surgery. Once inserted, it cannot be changed. Another surgery is required.
2. Programmable Valve Shunts: These are the most commonly used. The pressure level of these valves can be changed even after surgery. It does not require another surgery. The doctor adjusts this pressure level in his room, using a special magnet, which is placed on the skin.
Both types have been equally successful in clinical trials, but surgeons often choose the programmable type because it can be easily modified if needed.
How is the surgery to insert the shunt performed?
This surgery usually takes about an hour. You will not feel any pain because you will be given anesthesia, which means you will be completely asleep.
- First, a small section of hair is cut from a very small area of the head, a small incision is made in the skin, and a very small hole is made in the scalp.
- Then, the surgeon inserts one end of this shunt tube into a fluid-filled chamber inside the brain, called a 'ventricle' .
- The other end is passed under the skin, through the neck, and inserted into the abdominal cavity through a small incision in the abdomen.
- Finally, these incisions are closed with stitches or staples and bandaged.
After the surgery, you will be taken to a recovery room and carefully looked after by a nurse. When you wake up, you may feel a little tired and weak. You may also have a slight stomach ache. After a while, you will be transferred to a regular ward. As you gradually get better, you can get up, walk around, and start eating normally. If the doctor thinks you are ready to go home, you can go home in a day or two.
The important thing is that this shunt is not visible from the outside. But if you touch it, you can feel this plastic tube running under the skin of your neck.
How do you take care of the shunt after it is placed?
There is no special care required for the shunt on a daily basis. However , it is important to follow your surgeon's instructions and attend follow-up visits on a regular basis. Your doctor can then check the pressure level in the shunt to make sure it is working properly.
In addition, you should also be careful about the following things.
| Opportunity | What to do |
|---|---|
| If you ever have to have abdominal surgery | Inform your surgeon about your shunt so they can take the necessary precautions. |
| If you have ever had an abdominal infection (e.g. appendicitis) | Inform your doctor about that as well. |
| If you have a programmable shunt and need to have an MRI scan | On the day of your MRI, make an appointment with your doctor to recheck and adjust the shunt pressure. The magnetic strength of some MRI machines can change the shunt setting. |
When to see a doctor
If you have a programmable shunt and one or more of the following symptoms persist, see your doctor immediately and have the shunt pressure checked. These may be signs that the shunt is not working properly.
- Persistent headache
- Vomiting and nausea
- More sleepiness than usual
- Body weakness
- Seizures
- Difficulty speaking
- Balance problems
What are the risks of this?
A VP shunt is generally a very safe device, but like any surgery, there are some risks.
The main risk is infection. An infection in the shunt is a medical emergency. Your surgeon will clearly explain to you the signs of infection (such as fever, redness around the incision, swelling, pain) and what to do if it occurs. It is very important to follow those instructions exactly.
Another thing is that over time, the shunt can become blocked or malfunction. Then you will need another surgery to replace or repair it. The signs that the shunt is not working are often the same as the symptoms of hydrocephalus that you had before the shunt was placed. So if you experience any of these symptoms again, call your doctor right away.
What are the benefits of having a VP shunt?
When compared to these risks, the benefits of a VP shunt are very high.
- This usually resolves the symptoms of hydrocephalus within a few days.
- By removing dangerous pressure on the brain, it is possible to prevent permanent damage to the brain caused by pressure.
- You will have the opportunity to live a normal life again.
It may take several weeks or months to fully recover. Even after you are well, the shunt will remain in your body. It will not be removed.
Take-Home Message
- A VP Shunt is a thin tube that removes excess cerebrospinal fluid (CSF) from the brain and reduces pressure on the brain. It is an effective treatment for the condition Hydrocephalus.
- This surgery is generally safe. The shunt is not visible after the surgery.
- A shunt infection is a medical emergency. If you develop symptoms of infection such as fever, headache, or vomiting, go to a hospital emergency room (ETU) immediately or notify your doctor.
- If the symptoms that were present before the shunt was placed (headache, vomiting, difficulty walking) reappear, it may be a malfunction of the shunt. Call your doctor immediately.
- Never skip follow-up appointments with your doctor. It is very important for your health.
